  Vulnerability Insight:
  XFree86 is an implementation of the X Window System, which provides the
  core functionality for the Linux graphical desktop.
  
  Two integer overflow flaws were found in the XFree86 server's EVI and
  MIT-SHM modules. A malicious authorized client could exploit these issues
  to cause a denial of service (crash), or potentially execute arbitrary code
  with root privileges on the XFree86 server. (CVE-2007-6429)
  
  A heap based buffer overflow flaw was found in the way the XFree86 server
  handled malformed font files. A malicious local user could exploit this
  issue to potentially execute arbitrary code with the privileges of the
  XFree86 server. (CVE-2008-0006)
  
  A memory corruption flaw was found in the XFree86 server's XInput
  extension. A malicious authorized client could exploit this issue to cause
  a denial of service (crash), or potentially execute arbitrary code with
  root privileges on the XFree86 server. (CVE-2007-6427)
  
  An information disclosure flaw was found in the XFree86 server's TOG-CUP
  extension. A malicious authorized client could exploit this issue to cause
  a denial of service (crash), or potentially view arbitrary memory content
  within the XFree86 server's address space. (CVE-2007-6428)
  
  An integer and heap overflow flaw were found in the X.org font server, xfs.
  A user with the ability to connect to the font server could have been able
  to cause a denial of service (crash), or potentially execute arbitrary code
  with the permissions of the font server. (CVE-2007-4568, CVE-2007-4990)
  
  A flaw was found in the XFree86 server's XC-SECURITY extension, that could
  have allowed a local user to verify the existence of an arbitrary file,
  even in directories that are not normally accessible to that user.
  (CVE-2007-5958)
  
  Users of XFree86 are advised to upgrade to these updated packages, which
  contain backported patches to resolve these issues.


  Affected Software/OS:
  XFree86 on CentOS 2

  Fix: Please Install the Updated Packages.
